Estrogen and progesterone are the female hormones produced by the ovaries. These hormones cause monthly menstrual cycles to occur. These hormones also help eggs to develop in follicles, which are fluid-filled pockets, before an egg is released each month to travel down the fallopian tube. A third hormone, testosterone, also is produced by the ovaries in small amounts. Testosterone is in a broad class of hormones called androgens, and it is the dominant sex hormone in men. Between 4% and 7% of women produce too much testosterone in their ovaries.
During your menstrual cycle, the hypothalamus first releases GnRH. This causes a chemical reaction in the pituitary gland and stimulates the production of FSH and LH. Your ovaries produce estrogen, progesterone, and testosterone (yes, the male hormone) in reaction to stimulation by FSH and LH. When these hormones work harmoniously, normal menstrual cycles occur.
